AquaTwin

A 3D Digital Twin for Smart Water Management

AquaTwin is an intelligent digital twin system designed to simulate, monitor, and optimize smart water infrastructure. Leveraging Unity for real-time 3D visualization, LangChain-powered LLM agents for decision support, and a full-stack dashboard for system insights, AquaTwin provides a powerful tool for water resource management.
